We welcomed back Erik Seedhouse to the program to discuss the new Second Edition of “Tourists In Space: A Practical Guide.”  In our first segment of our 1 hour 26 minute show, Erik told us that the second edition was about 80% new and that it would be released the end of August.  If you buy the book on Amazon, you can order it at the special pre-release price.  Also, be sure to use the OGLF portal explained in the archive summary statement, on the blog and on both TSS & OGLF websites.  If you purchase it using the OGLF portal, Amazon makes a contribution to The Space Show.  Erik opened with the manual part of the book and mentioned his suborbital training company, Suborbital Training located in Melbourne, Florida.  For more information on suborbital training, visit http://www.suborbitaltraining.com.  Next, Erik talked about the flight profiles for both the XCOR Lynx and the Virgin Galactic SpaceShipTwo.  I asked Erik for the top 3 or 4 challenges to the industry and he cited space safety as the largest challenge to overcome.  Other top challenges included the spaceship noise which will be very loud, vibrations, acceleration, and space motion sickness.  He talked about the impact mostly on the cardiac system.  Erik was asked about the use of spacesuits with by the various companies.  We also discussed orbital space tourism using the Dragon and then later using the Dream Chaser.  Erik was asked if spaceflight participant medical exams would be done by special doctors or one’s own doctor even if the doctor has no aerospace expertise or experience.  Before the break & in response to a question, Erik pointed out that the industry was on hold given the all the earlier “cry wolf” announcements about starting revenue flights.

 

In the second segment, Erik talked about going to space at the designated and approved altitude by the FAI in France, the official international record and standards keeping organization for space issues.  He pointed out that 50 miles was not space.  We talked some about the World View project, then our topic switched to spaceports here in the U.S. as well as those planned for outside the country. Erik raised some red flags given the spaceships are under ITAR control which might make it very difficult for them to be operated in a foreign country under present ITAR rules/regulations.   Orbital tourism came up for Dream Chaser, Dragon V2 and the Bigelow Aerospace habs.  In speaking about the industry, our guest pointed out how SpaceX was changing spaceflight by their success.  The Brownsville, TX proposed SpaceX spaceport got lots of discussion time and email questions.  Erik pointed out two commercial spacesuit design companies, Orbital Outfitters and Final Frontier Design.  Near the end of our program, point to point transportation was discussed as were the potential winners in the upcoming commercial crew NASA down select process.

We welcomed Dr. Erik Seedhouse back to the show for this 1 hour 28 minute discussion regarding suborbital space and Erik’s new book, “Suborbital: Industry at the Edge of Space.”  In the first segment, Erik started out by telling why he wrote the book and he gave us updates regarding the prominent suborbital space companies.  We talked about payload flights, science flights, academic flights and space tourism flights.  Dr. Seedhouse spoke to the need to lower the cost for the flights and the need to prepare for painful accidents.  Listeners asked him to describe the flight profile for SpaceShip2 and the training many of the passengers had taken at the NASTAR Center.  Erik then spoke about competing centers, the American Astronautic Institute in Florida and Waypoint 2 Space which is adjacent to NASA JSC.  Questions came up about Astronauts4Hire and & the need to self market to get a flight.  Erik talked about floating free during the microgravity part of the flight on Virgin, addressing the issue of getting back to your seat on time before reentry.   Near the end of the segment, a listener asked why it was taking so long for suborbital flight we it was done decades ago and the information is in the public domain.  Ham the Chimp got mentioned in this section.  As the segment was closing, the new topic of space motion sickness came up.

In the second segment, a listener wanted to know if it mattered to the passenger re medical issues if vertical launch was used or horizontal launch was used.  Erik said the g force was the biggest medical problem with suborbital space.  He also talked about long arm centrifuge training, then he went over the Anti-G Straining Maneuver to deal with g force issues.  Space suits came, space tourist physical conditioning was discussion topic as was space radiation which Erik said was not a problem for suborbital flights.

Guest:  Dr. Erik Seedhouse.  Topics:  Dr. Seedhouse talked about his new book, “Pulling G: Human Responses to High and Low Gravity.”  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.  We welcomed Dr. Erik Seedhouse back to discuss his latest book, “Pulling G: Human Responses to High and Low Gravity.  I strongly recommend this book as it is a terrific resource on the subject of G-force on the human body.  If you buy it using this URL from Amazon, Amazon will make a contribution to The Space Show:  http://www.amazon.com/Pulling-Responses-Gravity-Springer-Popular/dp/1461430291/ref=onegiantlea20.  Our 1 hour 42 minute discussion was in two segments but as our topics overlapped segments, there will be no part one and part two for today’s program summary.  Dr. Seedhouse began the discussion talking about the different types and sources of gravity on the human body.  This included acceleration, lateral, reentry, vibrational, and more. We talked about helmet restraint issues, Formula One race cars and taking corners at high speed producing a high lateral G force, jet fighters, rocket flight, roller coasters, and more.  Erik went over the proposed flight profile in g terms for Virgin Galactic and other proposed vehicles.  He also talked about centrifuge research and findings with the general public at the NASTAR facility.  He then switched to g-load force, fighter pilots and the Anti-G straining maneuver and breathing that they do to help counter excessive g’s.  Suborbital flight came up and here, Dr. Seedhouse had much to say given the small amount of suborbital human spaceflight history.  We also talked about bone loss and density issues, osteoporosis, and obesity.  Erik said the best physical profile for resisting high g force was short and stocky.  The worst was tall and thin.  Don’t miss his explanation for this. He also said smokers do better in high g’s over nonsmokers.  Erik got lots of question about the Bill Weaver SR-71 ejection.  Then he mentioned the Armstrong Line and said above that point, blood boils without a pressure suit. Erik also talked about orthostatic intolerance (OI) in the context of g tolerance.  He talked about professional astronaut training for suborbital missions such as with Astronauts4Hire.  We then discussed the financial problems hitting the Canadian aerospace industry with layoffs, closures, and the possible sale of valuable space hardware.  Listeners wanted to know about anti g countermeasures, if any, and laser eye surgery was discussed although Erik said it was no longer a problem.
